Inventor: SHIMOKOSHI KIYOSHI
Filed: 1990-11-30
Abstract: PURPOSE:To calculate fluctuation of a delay of a cell with high accuracy by measuring a delay time of the cell in an asynchronous transfer mode(ATM) network and processing plural measured values statistically. CONSTITUTION:A clock 107 at a sender side gives transmission time information to each cell 113, a virtual path identifier/a virtual channel identifier(VPI/VCI) pool 108 gives information representing a measured path to each cell 113, a sample number (SN) counter 109 gives information representing a sample number to each cell 113 when plural cells are sent for each measurement and a transmission circuit 111 sends the result. A reception circuit 101 of a receiver side receives a cell 112, a clock 107 generates reception time information and a VPI/VCI-SN register 102 discriminates whether or not a cell received based on the information representing the measured path is addressed to itself, fetches only the cell addressed to itself, and a difference device 106 obtains time difference information between transmission time information of the fetched cell and the reception time information of the cell. Thus, fluctuation of a delay of a cell is measured with high accuracy.

Abstract: PURPOSE:To suppress wear in the power supply and to select and receive a frequency whose reception level is largest in average among plural frequencies by applying intermittent reception at a prescribed period. CONSTITUTION:When a power supply 9 is energized through a power key 13, its output is fed to a reception section 14 to cause the operating state.

Title: Digital circuit
Inventor: HASEGAWA YOSHIO
IPC: H03K21/00
Filed: 1990-11-29
Abstract: PURPOSE:To reduce the circuit scale by using a counter circuit and a shift register circuit in common. CONSTITUTION:An output signal Q1 of a FF1 (FF1-FFn are negative edge trigger operation flip-flops) is inverted at a trailing of a clock CK1 with a mode signal set to an L level, a signal Q2 inverted at the trailing of a clock input CK2 is outputted from a terminal Q of the FF2. Thus, output signals Q1-Qn represent an n-bit figure being a count of the clocks and the FFs act like a counter. With the mode signal set to an H level, a clock generator 10 gives clock signals CK1-CKn whose period is T to the FF1-FFn. A signal at the terminal Q is inputted to a terminal D of the FFn-1 through a multiplexer Sn-1 and a signal D having been inputted precedingly is transferred to the terminal Q. The signal having been inputted to the terminal D of each DFF is shifted respectively to the terminal Q in this way to be transited to a terminal D of an FF of a low-order bit, the value of the FF is outputted sequentially to the output terminal Q1 and the FF acts like a shift register. Thus, the circuit scale is reduced.

Filed: 1988-12-27
Abstract: PURPOSE:To ensure the optimum control of the picture quality of the input signal by controlling a noise elimination circuit with the output signal of an adder defined as a coefficient. CONSTITUTION:A detection signal 37 serves as the data having an amplitude K and produces such as a coefficient that satisfies 0<=L(K)<=1 (L: function of K), i.e., L is large and small when K is large and small respectively via a coefficient multiplier circuit 29. While a coefficient multiplier circuit 28 produces a coefficient (1-L). The noise elimination circuit 27-30 delay the output signals 20 by one frame to multiply them by the coefficient L and add them to the value obtained by multiplying the input signal 18 by the coefficient (1-L). Thus a cyclic noise elimination circuit is obtained. Thus the signal 37 of a non-standard detection circuit is used as a coefficient. As a result, the noise elimination circuit is effectively actuated in accordance with the non-standard degree of an input signal. Then the pictures of high quality can be obtained.
